Question 1

What is dolux.app's Open Graph type?

Accepted Answer

dolux.app declares `og:type` as `website`. This tells Slack how to categorize the content when generating a preview.

Question 2

Does dolux.app declare image dimensions?

Accepted Answer

dolux.app sets `og:image` but does not include `og:image:width` and `og:image:height`. Explicit dimensions let platforms render the preview faster without downloading the image first.

Question 3

What headline does dolux.app use for social previews?

Accepted Answer

dolux.app's social headline is "Dolux | Account and real estate investment by fractions" (55 characters).

Question 4

What description does dolux.app use for social previews?

Accepted Answer

dolux.app's social description reads: "Dolux is the financial app that combines accounts, real estate investment by fractions and the internal market with complete clarity." (133 characters).

Question 5

What site name does dolux.app display on social cards?

Accepted Answer

dolux.app sets `og:site_name` to "Dolux". This appears as a small attribution label on Facebook, LinkedIn, and Slack.

Question 6

What's the biggest issue with dolux.app's Slack preview?

Accepted Answer

Image won't fit social cards (512×512, 1:1). Your square-ish image will be cropped to 1.91:1 on Facebook, LinkedIn, and Slack, and to 2:1 on Twitter. Use 1200×630 (universal) or 1200×675 (Twitter-optimized) for predictable rendering.

Question 7

How can I improve dolux.app's social previews?

Accepted Answer

Review the recommendations above - they list specific issues and provide ready-to-paste meta tag snippets. The highest-impact fixes are usually a properly sized `og:image` (800×418), a clear `og:title` under 60 characters, and a 50-155 character `og:description`.
